New Zealand drivers Brendon Hartley and Earl Bamber have won the latest round of the World Endurance Championships in Germany to extend their overall lead.
A month after their triumph at the famed Le Mans 24 Hours race, Hartley, Bamber and German Timo Bernhard combined to win the 6 Hours of Nurburgring.
The result pushes the Porsche trio 30 points clear of their nearest rivals from Toyota after four of nine rounds in the WEC.
Their toughest competition on Sunday came from the second Porsche hybrid car in the LMP1 class driven by Andre Lotterer, Neel Jani and Nick Tandy.
The two teams were rarely more than 10 seconds apart throughout the 204-lap journey, with a gap of just 1.606 seconds separating them at the chequered flag.
Bamber enjoyed the battle, which was effectively decided when his car spent less time in the pits than their rivals when both stopped for a late fuel top-up.
"Our car was stronger on new tyres and the other car came on stronger later, but it was also about aero degradation," he said.
"One minute we'd have the problem and then they would have it."
The fifth round is in Mexico in September.
